Single line beamer slide

Question

This probably isn't how beamer is intended to be used.

However, I would like to create a beamer slide where:

• there is only a single line in the slide/frame
• the single line is vertically and horizontally centered

• the single line has the exact same style as the frame title

  I'm using \usetheme{default} so there's no magic going on. (The frametitle is just some font in a light blue color.)

  What is the dumbest way I can achieve this? (I see that there are "title slides" -- but I want many of them, and I don't want the author part. I see also that I can use \frametitle in a frame ... but it's stuck at the top of the frame.)

  I'm looking for something that's equiv to:

  \newpage
  \vspace*{\fill}
  \hspace*{\fill}...\hspace*{\fill}\vspace*{\fill}
  \newpage
  

but in beamer.

Answer 1

You can use the frametitle font and color; by default the text will be vertically centered, so you only have to add \centering to center the text horizontally:

\documentclass{beamer}

\begin{document}

\begin{frame}
\frametitle{Test frame}
\usebeamerfont{frametitle}\usebeamercolor[fg]{frametitle}
\centering
A line of text
\end{frame}

\end{document}

Answer 2

I think this is what you want (essentially combining both of Gonzalo's answers together):

\documentclass{beamer}
\usetheme{default}
\setbeamertemplate{frametitle}{}
\newenvironment{myline}
  {\usebeamerfont{frametitle}\usebeamercolor[fg]{frametitle}\vfill\centering}
  {\par\vfill}
\begin{document}
\begin{frame}{}
\begin{myline}
This is a single line of text.
\end{myline}
\end{frame}
\end{document}
